Lockout is set in an old Forerunner research lab on Delta Halo. It's a tight space that revolves around close quarters combat, with narrow corridors and three levels.

The remastered version was designed by Max Hoberman, president of co-developer Certain Affinity and one of the original lead designers of Halo 2.

"Lockout was hands-down the most popular small arena-style map in Halo 2," he said.

"We're thrilled to be bringing this fan-favourite back, and are paying close attention to the details and subtleties that made the original great while also making a couple of very careful, very calculated enhancements.

"Most prominent among these are a bit of cover added to the 'Elbow,' the long walkway connecting the grav lift to the sniper tower, and a dynamic element that should help counter an entrenched group of enemies. Of course this can be disabled in Forge for players who want a near-match of the original experience."
